Barwon Region Water Corporation has applied to Environment Protection Authority Victoria (EPA) for a development licence to upgrade its treatment plant at Colac.
It is proposed overall capacity at the existing wastewater treatment facility would increase from 5.7ML/day to 7 ML/day.
The application states the upgrade will cater to population growth and increased industrial activity in the area.
Treated effluent will be discharged to Colac Lake using the existing facility. The existing licence discharge limits for most of the parameters will be maintained and reduced.
The proposed upgraded plant will result in lower median concentrations of nutrients, but in a higher volume, with an increase in total nitrogen load and a decrease in total phosphorus load at the maximum discharge volume.
The upgrade will increase the number of plant process units and upgrade some of the existing facilities within the existing plant.
Community consultation is open until 25 October 2021 at www.engage.vic.au/epa-works-approvals/barwon-water
